青岛市生态环境质量动态变化研究简

以2011年Landsat TM遥感影像为基础数据源，利用遥感与GIS技术对青岛市生态环境状况进行了监测，依据《生态环境状况评价技术规范（试行）》（HJ/T 192-2006）对2000-2011年生态环境质量动态变化趋势进行了评价，在此基础上对地市级单位进行生态环境质量评价中存在的主要问题进行了分析。指出使用归一化系数评价不同区域同一时期的生态环境状况是有效的，但同一区域不同时期的同一指标却不具有可比性；地市级单位在应用规范的过程中发现，不能将“区”作为和“县”同级的评价单元； COD对环境的污染影响应与区域降水的总量负相关，在对COD负荷进行评价时，应考虑的是区域的降水总量。

Research on Dynamic Changes of Eco-environmental Quality in Qingdao City

Remote sensing and GIS technology were used for monitoring ecological and environ-mental conditions in Qingdao City. According to the Technical Criterion for Eco-environmental Status Evaluation （Trial Implementation）, the situation and changing trends of ecological environ-ment in Qingdao from 2000 to 2011 were evaluated. Some issues for city-level unit existing in the ecological environmental quality assessment related to the technical criterion were analyzed. Eval-uation of ecological environment in different areas of the same period using the normalized coeffi-cient is effective, but the same index in the same area of different period is not comparable. In the process of evaluation, ＆quot;zone＆quot; and ＆quot;county＆quot; can＆#39;t be considered as the same unit. Effect of COD on environmental pollution has negative correlation with total amount of regional precipitation. So in the evaluation of COD load, total regional precipitation should be considered.
